7¹³ = 7*7*7*7*7*7*7*7*7*7*7*7*7
       |__________________________
        <span>seventeen sevens

7</span>¹³ = 7¹⁺¹² = 7*7¹²
7¹³ = 7²⁺¹¹ = 7²*7¹¹
7¹³ = 7³⁺¹⁰ = 7³*7¹⁰
7¹³ = 7⁴⁺⁹ = 7⁴*7⁹
7¹³ = 7⁵⁺7⁸ = 7⁵*7⁸
7¹³ = 7⁶⁺7⁷ = 7⁶*7⁷

<span>You can also break down so
</span>7¹³ = 7²⁺²⁺⁹ = 7² * 7² * 7⁹

<span>the possibilities are many :)</span>

As an example, 15,000 Men 18-34 watched program X at 7-8 pm on Monday night. 32,000 Men 18-34 had their TV on during the same ti
miv72 [106K]

Answer:

7.5 rating points

Step-by-step explanation:

The computation of the rating for Men 18-34 for program X is shown below:

Given that

Number of men 18 -34 watched a program X = 15,000 = X

Number of men 18 - 34 watched in a same time = 32,000

And, the total households in the market = 200,000 = Y

So, the rating for men 18-34 for program x is

= \frac{X}{Y}

= \frac{15,000}{200,000}

= 7.5 rating points

We simply applied the above formula

Mr. Malloy wants to make sure Amo and Javier get the best possible grade after five tests and can either give a grade based on t
joja [24]
The data has been properly arranged in tabular form and is shown below in the image.

First we need to find the mean and median of scores of both students.

1) For Amo:
Mean = \frac{97+92+89+55+90}{5}=84.6
Median = Middle Value when data is arranged in ascending order = 90

2) For Javier:
Mean =\frac{68+97+65+92+95}{5}=83.4
Median = Middle Value when data is arranged in ascending order = 92

For both the students, value of Median is larger then the mean. So in order to give the best possible grade Mr. Malloy should use the median score for both students.

Nina can ride her bike 63,360 feet in 3,400 seconds, and Sophia can ride her bike 10 miles in 1 hour . What is Nina’s rate miles
faltersainse [42]

Answer:

Nina's rate in miles per hour is 2.7 miles/hour

Nina bikes faster

Step-by-step explanation:

we know that

1 hour=3,600 seconds

1 mile=5,280 feet

<em>Convert feet to miles</em>

63,360 feet=63,360/5,280=12 miles

Convert seconds to hours

3,400 sec=3,400/3,600=0.94 hours

Find Nina's rate in miles per hour

12/0.94=12.7 miles/hour

Sophia's rate in miles per hour is 10 miles/hour

Compare the rates

12.7 miles/hour > 10 miles/hour

therefore

Nina bikes faster

Write and solve an equation of ratios:

900 students      45 teachers         
------------------  = -----------------  
          x               110 teachers     

Cross multiplying, we get (900)(110) / 45, or

                                                                 
so x = # of students in the high school = 2200   (answer)
